I will describe our new lattice action using Möbius Domain Wall Fermions (MDWFs). The gauge action is tree-level Symanzik-improved with a rectangle coefficient of \(c_1=-1/12\) and bare coupling \(\beta\). The four flavors of MDWF utilize a Dirac operator with 8 iterations of Stout link smearing with \(\rho=0.125\), which is comparable to gradient-flow smearing radius of 1 in lattice units. A domain-wall height of \(M_5=1.0\) is used for all \(\beta\) and \(L_5\) and the \(b\) and \(c\) Möbius parameters are tuned to keep \(m_{\rm res}\) MeV on all ensembles. With a modest allocation on Perlmutter at NERSC, we have generated more than 30 ensembles spanning \(135\lesssim m_\pi \lesssim 460\) MeV and \(0.05 \lesssim a \lesssim 0.12\) fm. Details of the HMC integrator, topological charge, gradient flow scales, autocorrelation times and other details will be provided. The configurations used in arXiv:2605.06560 are publicly available via globus as described in the preprint.
